Why choose Edexcel qualifications?Pearson – the world’s largest education companyEdexcel academic qualifications are from Pearson, the UK’s largest awarding organisation.With over 3.4 million students studying our academic and vocational qualificationsworldwide, we offer internationally recognised qualifications to schools, colleges andemployers globally.Pearson is recognised as the world’s largest education company, allowing us to driveinnovation and provide comprehensive support for Edexcel students to acquire theknowledge and skills they need for progression in study, work and life.A heritage you can trustThe background to Pearson becoming the UK’s largest awarding organisation began in 1836,when a royal charter gave the University of London its first powers to conduct exams andconfer degrees on its students. With over 150 years of international education experience,Edexcel qualifications have firm academic foundations, built on the traditions and rigourassociated with Britain’s education system.Results you can trustPearson’s leading online marking technology has been shown to produce exceptionallyreliable results, demonstrating that, at every stage, Edexcel qualifications maintain thehighest standards.Developed to Pearson’s world class qualifications standardsPearson’s world-class standards mean that all Edexcel qualifications are developed to berigorous, demanding, inclusive and empowering. We work collaboratively with a panel ofeducation thought leaders and assessment experts to ensure that Edexcel qualifications areglobally relevant, represent world-class best practice and maintain a consistent standard.For more information on the world class qualification process and principles, please go toAppendix 2: Pearson World Class Qualification design principles or visit our gn-principles.html4Pearson Edexcel International GCSE in Physics –Specification – Issue 1 – June 2016 Pearson Education Limited 2016

Why choose Pearson Edexcel International GCSE inPhysics?We’ve listened to feedback from all parts of the International and UK school subjectcommunity, including a large number of teachers. We’ve made changes that will engagestudents and give them skills that will support progression to further study in physics and arange of other subjects, in physical sciences and elsewhere. Our content and assessmentapproach has been designed to meet students’ needs and be consistent with our approachacross the sciences.At Pearson we offer separate science qualifications in Biology, Human Biology, Chemistry andPhysics, as well as Double Award and Single Award Science qualifications – these have beendesigned to meet different students’ needs. The content and assessment approach in all ourscience qualifications has been designed to meet students’ needs in the following ways. Content that is interesting and engaging for students but is also designed to ensure goodpreparation, both for those continuing to further study and for those wishing to work in aphysics-related field. There are opportunities to ‘localise’ the content to make it more relevant for students intheir own country. Question papers are clear and straightforward – our question papers are clear andaccessible for all students of all ability ranges and learning styles. Our mark schemes arestraightforward, so that the assessment requirements are clear. Students’ skills are broadly developed – we have designed the International GCSE toextend students’ knowledge by broadening and deepening skills, for example:–developing students’ practical skills by including a number of practicals in thespecification content. These can be supplemented with other suggested practicals.The skills developed will be assessed through questions in written examinations–improving students’ analytical and logic skills by applying understanding of scientificconcepts and principles to a range of situations. This will include some examinationquestions that are more problem solving in style–addressing the need for mathematical skills to complement students’ physics skillsby covering a range of mathematical areas.Progression to A Level – International GCSEs enable successful progression to A Level andbeyond. Through our World Class Qualification development process we have consulted withInternational Advanced Level and GCE A Level teachers as well as higher educationprofessors to validate the appropriateness of the qualification, including its content, skillsdevelopment and assessment structure.Courses to suit your students’ needs and interests – teachers of physics have a choiceof International GCSE courses to deliver, each giving different levels of depth to meetstudents’ needs. As well as the Pearson Edexcel International GCSE in Physics, students canalso be taught our International GCSE in Science (Double Award) or our International GCSEin Science (Single Award). These courses offer a reduced amount of content, but areassessed to the same standard. Progression routes for these courses may vary slightly fromthose for the Pearson Edexcel International GCSE in Physics.More information about all our qualifications can be found on our Edexcel InternationalGCSE pages at qualifications.pearson.comPearson Edexcel International GCSE in Physics –Specification – Issue 1 – June 2016 Pearson Education Limited 20165
